Hello, I'm still configuring the new server. The 456 error is resolved, thanks, but now I have a new problem.
Looking at log files, it seems local delivery is ok. Here is an example of my logs for a test message from GMail to i...@usosalix.com: May 14 01:05:57 maxwell courieresmtpd: started,ip=[::ffff:10.7.33.100] May 14 01:05:59 maxwell courierd: newmsg,id=000000000060075F.0000000059179156.00007FBD: dns; mail-pf0-f175.google.com ([::ffff:10.7.33.100]) May 14 01:05:59 maxwell courieresmtpd: The TLS connection was non-properly terminated.

E.g. no files written into the Maildir, despite the "Message delivered" log. I've also tried to access the Maildir with Thunderbird and RoundCube and they both confirm there aren't any messages. I have no clue about what I should check... please help. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
